Probably the best way is for you to have a BMS that directly controls the charging sources and instead of just disconnecting the batteries, it would stop the charging and/discharging by signalling...

I didn't really see much on there about spikes not happening, just that loads will prevent damage and no load it won't matter. In particular the no loads shows a complete lack of knowledge about how...

Spikes are transient, AFAIK and can be very short. Loads will dissipate a surge but I just can't see any fragile electronics surviving it sometimes. Without a battery to provide a voltage reference...

I assume you are referring to the solar potentially going to high voltage if the batteries disconnect.


The deal is, if the batteries go off line the solar controller can't do anything because it...

That certainly can be an issue and is why the better control systems shut of the charging sources rather than shut down battery itself. This has been discussed here before in relation to control...

I also found it a bit misleading or confusing, and it is now obvious to me why.


In the past, nearly all the talk about battery bank size centered around capacity of the bank and charging time...

Some manufacturers do still say you can use 100% of lithium capacity, but many have backed off that and recommend about 10% on each end, top and bottom. It is said to increase cycle life and help...

The pretty much covers it. The high amp draw is what makes the usable lower with AGM than lithium, but only while the high amps are being drawn. The amount of power they both lose is the same so at...

The 12v input current can pull down the input voltage to low enough to trip the inverter low voltage input shutdown switch and that ends the inverting.

Re the ventilation while driving.

The underbody of the van is a very hot area and likely too hot for lithium batteries, that are more sensitive, it appears, than AGM are. If hung underneath you would likely need to encase and...

No rewiring normally needed to do that. Most B's all you need to do is put in a switchable separator instead of an isolator or auto connect only separator.

200 amps for an Onan starter sounds way high to me.


Our Onan, when we had one, was on a 10ga wire which is horribly inadequate for 200 amps. Our van had 80 amp breakers from the engine to back...
